JOHN T. BLACK, OF PHILADELPHIA, PENNSYLVANIA.

- HYDROCARBON-OIL BURNER.

SPECIFICATION forming part of Letters Patent No. 437,013, dated September 23, 1890.

Application filed May 17, 1890. Serial No. 352,162. (No model.)

.To aZZ whom it may concern:

Be it known that I, J OIIN T. BLACK, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Hydrocarbon-Oil Burners, of which the following is a specification.

The object of my invention is to construct a burner for burning hydrocarbon oils in combination with air, especially applicable for use in connection withmetal-heating furnaces; but it will be understoodthat it can be used in connection with any furnace or heater in which an intense heat is required.

Int-he accompanying drawings, Figure 1 is a side View of the burner. 2 is a longitudinal sectional view. Fig. 4 is a section on the line 1 2, Fig. 2, and Fig. 5 is a View showing the application of the burner to a heating-furnace.

A is the burner proper, supported by a standard a, secured to the furnace or to the foundation in any suitable manner.

I) is the oil-pipe, secured in the present instance to the rear of the burner, and is provided with a suitable valve 1).

c is the air-pipe, having a valve 0 and provided with two branches 0 the branch 0 entering the burner at or about the middle thereof, and the branch 0 connected to the burner at or near the vrear end. The pipe 0 preferably passes through the stack or other suitable heater, in order to supply-hot air to the burner.

The end of the burner projects into a chamber d, which is connected to the pit in the present instance by a pipe 61. As the vapor passes out of the burner it combines with the air from the chamber cl, taking up sufficient air therefrom to insure proper combustion.

The details of the construction of the burner are as follows, reference being had to Figs. 1 to 4, inclusive: B is the four-way coupling, the lower branch I) being secured in the present instance to the standard a. The upper branch e is secured to the air-tubes c and the forward branch 6 is secured to the nozzle D, while the rear branch 6 is secured to the block E. In the block E is an orifice f, in which is tapped the air-pipec Secured to the forward end of the block E is a tube F,

Fig. 3 is an end VIGW;

extending nearly to the end of the nozzle D. At the end of this tube F are a series of small tubes 9. The tube F is adjusted centrally in the nozzle by means of set-screws h, the nozzle being reduced in diameter at the outlet end 2' to form a narrow passagefor the air issuing from the tube 0 A plate G is secured to the block E in the present instance by screws j. This plate has a nipple, to which is attached the oil-inlet pipe I). Secured to this plate is a small oil-pipe m, passing into the tube F, as shown in Fig. 2.

The operation of the burner is as follows: Oil is admitted into the burner from the pipe I) through the pipe m. The hot air from the tube c entering the burner through the tube F, separates the oil as it drops from the pipe 'm and forces it out in particles through the small passages g, and at thesame time the air passes through the nozzle surrounding the passages, forming an annular current of air around the central current of air and oil forced out through the small passages g, thus giving the necessary amount of air for proper combustion.

I have found that by this special construction of burner an intense heat can be main tained, which can be readily regulated by simply operating the several valves of the air and oil pipes.

I claim as my invention- 1. The combination, in an oil-burner, of the block, a tube F, projecting therefrom, having at its outer end a number of small orifices, a nozzle D, an air-inlet therefor, said nozzle sur rounding the tube F, an oil-pipe m, extending into the tube F, the whole being arranged so that oil as it passes from the pipe at is carried and separated by the air and forced through the tube F, substantially as described.

2. The combination,in an oil-burner, of the four-way coupling, the air-tube secured thereto, the nozzle D, secured to the forward branch inlet in the coupling, a tube extending from the block through the coupling and into the nozzle, said tube having at its outer end a number of smaller tubes,a plate adapted to the block, and an oil-tube projecting; therefrom and into the block and tube, substantially as described.

4. The combination of the four-way coupling, the air-pipe secured thereto, nozzle 1), projecting therefrom and reduced at its outer end, a block E, secured to the rear of the coupling, an air-inlet therein, and a tube F, projecting from the block into and through the coupling and into the nozzle to and into its reduced end, leaving an air'space surrounding the pipe F, with an oil-pipe projecting through the block E into the pipe F, said tube having small passages through which the oil is forced, substantially as specified.

5. The combination of the four-Way coupling, a standard adapted to one extension thereof, an air-pipe adapted to another extension, a nozzle and a block secured to opposite extensions, an air-inlet in the block, and an oil-pipe passing through the block, the whole arranged substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
